What does it mean to brace a wall?
Wall bracing is used to protect life by minimizing structural damage to a building in freak storms and earthquakes. All buildings are required to have some form of lateral bracing. Exterior and interior wall coverings are usually used with conventional light-frame construction.
What is brace wall framing?
A braced frame is a really strong structural system commonly used in structures subject to lateral loads such as wind and seismic pressure. The members in a braced frame are generally made of structural steel, which can work effectively both in tension and compression.

Why is bracing used in construction?
A bracing system is a secondary but essential part of a bridge structure. A bracing system serves to stabilize the main girders during construction, to contribute to the distribution of load effects and to provide restraint to compression flanges or chords where they would otherwise be free to buckle laterally.
What is braced frame construction?
A braced frame is a structural system that is prevented from undergoing excessive sidesway under the effect of lateral loads by the provision of diagonal steel members (for steel structures) or shear walls/cores (for reinforced concrete structures).

Some internal walls are also load-bearing, so altering or removing these may reduce a building's compliance with the Building Code's structural performance requirements.

Why do we need shear bracing?
Outside walls on both commercial and residential applications require some sort of shear bracing. This is to prevent the wall from “racking”. This sort of bracing gives a building a large percentage of its overall strength so it is very important this is done right. Some walls are designed specifically by engineers to be placed in a certain location to add strength to a structure and are termed “shear walls”. Close attention should be payed to the blueprints on such walls because they may call for a specific size and type of structural panel such as 3/4″ CDX.
Can you orient a deck panel?
You would not orient panels in such a manner if you were decking a roof, the weakness would be obvious. It is also easier to straighten the studs when the sheets are run horizontally. However 90% of builders will do just the opposite.
Do you need to plumbed a wall before bracing?
Before any wall bracing of any kind can be done, every corner must plumbed and the walls should be straightened. Make certain all offsets line up or are at least parallel. Remember that to establish a continuous panel from top to bottom a row of blocking in the stud wall must be installed and each panel nailed into it.
Is it a sin to turn a structural panel?
It is also practically a sin to turn structural panels, with a strength axis, upright on a stud wall. This does very little to keep the studs from crowning and if exposed to moisture, then it runs the risk of the panel itself warping. You would not orient panels in such a manner if you were decking a roof, the weakness would be obvious.
